Mathematical modeling of extra-heavy oil gasification at different fuel water contents

Effect of Torrefaction Temperature, Residence Time and Particle Size on the Properties of Torrefied Food Waste

“…Besides that, the elemental analysis was obtained by CHNS Element Analyzer Macro Elemental to determine the weight percentage of elemental carbon, hydrogen, nitrogen, sulfur, and oxygen (by difference) in the samples. Furthermore, heating value is calculated based on the formula [7] by using the results of weight percentages of the elemental carbon, hydrogen, nitrogen, sulfur, and oxygen obtained from CHNS Element Analyzer as shown in Eq. 1:…”

Emerging technologies for catalytic gasification of petroleum residue derived fuels for sustainable and cleaner fuel production—An overview

“…H 2 O or CO 2 , are not uniformly distributed within the reactor and during the preheating and vaporization. Thermal pyrolysis of heavy hydrocarbons, in addition to the production of black carbon as the ultimate product, also produces aromatics and olefins, which tend to condense for tar or wax, especially since the temperature within the reactor or its inlet and outlets is not within the appropriate range for their condensation (Ghassemi et al, 2015;Weiland et al, 2021).…”

Experimental and Numerical Evaluation of Hydrogen Production Potential through Gasification of Thermochemical Fluid-Stimulated Bitumen under CO2-Rich Oxidants

“…In addition, Vaezi et al 15 simulated the performance of heavy fuel oil gasifier by combining both chemical and thermodynamic equilibriums of the global gasification reaction, while Gomez et al 18 proposed a kinetic modeling to describe gas-phase partial oxidation reaction to predict H 2 generation through filtration combustion of a modeled heavy oil in a 2-dimensional packed bed reactor. Moreso, by combining kinetic models and reaction equations for in situ combustion and gasification of heavy oil, Song et al 25 presented numerical modeling and simulation of hydrogen generation from heavy oil considering reaction temperature and water injection rates, while Ghassemi et al 21 conducted mathematical modeling of extra-heavy oil gasification at different fuel-water contents through a steady-state model based on global reaction kinetics. On the other hand, the computational modeling and simulation approaches, otherwise referred to as CFD, have been employed by Araya et al, 19 Lan et al, 20 and Watanabe et al 14 to evaluate H 2 generation from gasification of heavy fuel oil and/or asphalt emulsion (typically, extra-heavy oil or bitumen emulsion).…”

“…Apart from experimental studies, H 2 production potential from heavy oil has been explored through numerical modeling and simulation approaches. − Gasification modeling generally offers the advantage of understanding various phenomena that might be difficult using an experimental approach alone. As is available elsewhere in the literature, a gasification system design is typically done using different methods, including the black-box model, which is a zero-dimensional thermodynamic model involving mass and energy balances over the entire gasification reactor.…”
